Dvar,
Which code are you running? Do you have a rule that says "Allow_ftp_AV"?
If so, change the SERVICE on that rule to ftp from FTP_AV. The newer code on the 210 allows for UTM services and the default FTP rule becomes the above. If that happens it'll block all external FTP by default until you change that service within that rule. (Or you can delete it and rewrite it)
